Endress+Hauser Levelflex FMP51-AAACBBLAA4AEJ+AALA
Guided Radar Level Transmitter
The Endress+Hauser FMP51-AAACBBLAA4AEJ+AALA is a Levelflex FMP51 series guided wave radar level transmitter, designed as the standard sensor for the most demanding liquid level measurement applications . It delivers reliable, continuous measurement of liquids, pastes, and slurries, as well as interface measurement, even under extreme process conditions like high temperature, high pressure, turbulent surfaces, foam, or when tank baffles are present .
The measurement is unaffected by changing media properties, temperature fluctuations, gas blankets, or vapors . Featuring Heartbeat Technology, HistoROM data management, and Multi-Echo Tracking evaluation, the FMP51 ensures maximum reliability, easy commissioning, and cost-effective plant operation throughout its entire life cycle .

FAQs
Q1: What is the measurement accuracy of the Levelflex FMP51-AAACBBLAA4AEJ+AALA?
A: The FMP51 provides a high accuracy of ±2 mm (±0.08 in) for rod probes and rope probes up to 15 meters (49 ft). This ensures precise and reliable level measurement for demanding applications .
Q2: What makes the FMP51 suitable for extreme process conditions?
A: The FMP51 is designed for the process industry and can withstand extreme conditions such as temperatures from -50 to +200°C and pressures up to 40 bar (580 psi) . Its robust construction and Multi-Echo Tracking evaluation ensure stable measurement even with turbulence, foam, or tank baffles .
Q3: Can the FMP51 measure the interface between two liquids?
A: Yes. The FMP51 is capable of interface measurement . This requires that the dielectric constant (DC) of the upper medium is known and constant, its DC is not greater than 10, and the DC difference between the upper and lower medium is greater than 10.
